<First embodiment>
First, the fixture and arrangement | positioning body fixing device of 1st embodiment of this invention are demonstrated based on FIG. 1 thru | or FIG.
In FIG. 1 to FIG. 5, the arrangement body fixing device 1 is used for providing a pipe hole for inserting a pipe in a concrete wall of a building in the thickness direction. The tubular sleeve 41 for forming is fixed to the reinforcing bar 32 at a predetermined distance. The arrangement body fixing device 1 includes a fixture 11 for fixing a sleeve 41 as an arrangement body to a reinforcing bar 32 that is a bar 31 constituting a structure, and an arrangement body support portion 23 that supports the sleeve 41. And a bolt body 21 having an external thread 22 on the outer surface.

固定具11は、図3に示すように、1本のばね性を有する材料である金属製の断面円形の線材を折り曲げて形成されており、両端部に鉄筋32に固定するための固定部12を有し、中央部にはボルト体21を保持する保持部13を備えている。各固定部12と保持部13とは、直線状の連結部14で連結されている。固定部12は、鉄筋32に掛け止めするための掛止部15を備え、掛止部15は線材を円弧をなすフック形状に折り曲げて形成されている。ここで、掛止部15は、鉄筋32への掛止を容易ならしめるため、挿入開口15aは鉄筋32の外径より僅かに大きく形成されている。   As shown in FIG. 3, the fixture 11 is formed by bending a metal wire having a circular cross section, which is a spring material, and a fixing portion 12 for fixing the reinforcing bars 32 to both ends. And a holding portion 13 for holding the bolt body 21 is provided in the center portion. Each fixing portion 12 and the holding portion 13 are connected by a linear connecting portion 14. The fixing portion 12 includes a hooking portion 15 for hooking the reinforcing bar 32, and the hooking portion 15 is formed by bending a wire rod into a hook shape forming an arc. Here, the insertion portion 15 is formed to be slightly larger than the outer diameter of the reinforcing bar 32 so that the engaging part 15 can be easily locked to the reinforcing bar 32.

保持部13は、線材をコイル状に複数巻回して形成され、その内径はボルト体21の雄ねじ部22の外径より僅かに大きく形成され、内部を雄ねじ部22が軸方向に移動可能となっている。一方で、保持部13は、線材を更に少し巻回する、即ち後述するように固定部12を鉄筋32に固定したとき、コイルの内径はボルト体21の雄ねじ部22の外径より小さい大きさに縮径されて雄ねじ部22に係合するように形成されている。即ち、保持部13のコイルの内面部には雄ねじ部22に係合する係合部16が形成されていて、縮径によって係合部16の線材の一部は、ボルト体21の雄ねじ部22の谷部内に嵌入して係合し、これにより、保持部13の内部をボルト体21の雄ねじ部22が軸方向に移動するのが阻止されるようになっている。ここで、保持部13の線径とボルト体21の雄ねじ部22のねじピッチとが同一寸法の場合は、保持部13の係合部16とボルト体21とをより効果的に係合させることができる。
更に、保持部13は、係合部16がボルト体21の雄ねじ部22に係合した状態では、ボルト体21に強く圧接してボルト体21が係合部16に対して軸を中心に回動するのを防止している。
The holding portion 13 is formed by winding a plurality of wire rods in a coil shape, and its inner diameter is formed slightly larger than the outer diameter of the male screw portion 22 of the bolt body 21, and the male screw portion 22 can move in the axial direction inside. ing. On the other hand, the holding part 13 winds the wire further a little, that is, when the fixing part 12 is fixed to the reinforcing bar 32 as described later, the inner diameter of the coil is smaller than the outer diameter of the male screw part 22 of the bolt body 21. And is formed so as to be engaged with the male screw portion 22. That is, an engaging portion 16 that engages with the male screw portion 22 is formed on the inner surface portion of the coil of the holding portion 13, and a part of the wire rod of the engaging portion 16 is reduced due to the reduced diameter. This is inserted into and engaged with the trough portion, thereby preventing the male screw portion 22 of the bolt body 21 from moving in the axial direction inside the holding portion 13. Here, when the wire diameter of the holding portion 13 and the screw pitch of the male screw portion 22 of the bolt body 21 are the same size, the engaging portion 16 of the holding portion 13 and the bolt body 21 are more effectively engaged. Can do.
Further, in a state where the engaging portion 16 is engaged with the male screw portion 22 of the bolt body 21, the holding portion 13 is strongly pressed against the bolt body 21 so that the bolt body 21 rotates about the axis with respect to the engaging portion 16. To prevent movement.

固定具11の両側の直線状の連結部14は、図2(a)に示すように、平面視で交差する部分の保持部13とは反対側の開き角度イは、180度より小さく形成され、図2(a)では、165度に形成されている。また、各固定部12の掛止部15は連結部14に直交する方向より少し外向きに開いた状態で円弧をなすフック形状に折り曲げられている。このように折り曲げられた掛止部15は、固定具11を鉄筋32に固定した後は、図5に示すように、鉄筋32に直交して掛止され、固定具11は安定して鉄筋32に固定されることになる。   As shown in FIG. 2 (a), the linear connecting portions 14 on both sides of the fixing tool 11 are formed so that the opening angle i on the side opposite to the holding portion 13 at a portion intersecting in plan view is smaller than 180 degrees. In FIG. 2A, it is formed at 165 degrees. In addition, the latching portion 15 of each fixing portion 12 is bent into a hook shape that forms an arc in a state of opening slightly outward from the direction orthogonal to the coupling portion 14. After fixing the fixing tool 11 to the reinforcing bar 32, the hooking part 15 bent in this way is hooked perpendicularly to the reinforcing bar 32 as shown in FIG. 5, and the fixing tool 11 is stably stabilized. It will be fixed to.

次に、ボルト体21は、外面に雄ねじ部22を備えているとともに、雄ねじ部22の一端部には、配設体であるスリーブ41を支持するための配設体支持部23が連結されている。雄ねじ部22は、少なくとも配設体支持部23を鉄筋32から所定距離離間させて固定できるに足る長さを有している。   Next, the bolt body 21 includes an external thread portion 22 on the outer surface, and an arrangement body support portion 23 for supporting a sleeve 41 as an arrangement body is connected to one end portion of the external thread portion 22. Yes. The male screw portion 22 has a length sufficient to at least fix the arrangement body support portion 23 at a predetermined distance from the reinforcing bar 32.

一方、配設体支持部23は、連結端部が雄ねじ部22の一端部に外嵌して取着される支持部本体24と、スリーブ41を結束して支持する結束バンド26とで構成されている。配設体支持部23は、支持部本体24に貫設されたねじ孔24aに固定ねじ25が螺着され、固定ねじ25の先端が雄ねじ部22の外面に押し付けられることにより、雄ねじ部22の所定位置に固定されるようになっている。なお、支持部本体24においてねじ孔24aが設けられた側面と直交する上面には矩形窓24bが設けられており、この矩形窓24bから固定ねじ25の先端が雄ねじ部22に当接した状態を視認することができる。支持部本体24は、スリーブ41の外周壁に沿って当接する円弧板状の配設体当接部24cを備えており、配設体当接部24cの長さ方向両端部の上下には、結束バンド26の巻回方向を案内するとともに支持部本体24から外れるのを防止する案内突起片24dが外周方向に向けて一体に突設されている。支持部本体24は、合成樹脂等によって一体に形成されているが、複数に分割して形成してもよい。   On the other hand, the arrangement body support portion 23 includes a support portion main body 24 whose connection end portion is fitted and attached to one end portion of the male screw portion 22, and a binding band 26 that binds and supports the sleeve 41. ing. In the arrangement body support portion 23, a fixing screw 25 is screwed into a screw hole 24 a penetrating the support portion main body 24, and the tip of the fixing screw 25 is pressed against the outer surface of the male screw portion 22. It is fixed in place. In addition, a rectangular window 24b is provided on the upper surface orthogonal to the side surface in which the screw hole 24a is provided in the support body 24, and a state in which the tip of the fixing screw 25 is in contact with the male screw portion 22 from the rectangular window 24b. It can be visually recognized. The support portion body 24 includes an arcuate plate-like arrangement body abutting portion 24c that abuts along the outer peripheral wall of the sleeve 41, and above and below the both ends in the length direction of the arrangement body abutting portion 24c. A guide protrusion 24d that guides the winding direction of the binding band 26 and prevents the binding band 26 from being detached from the support portion main body 24 is integrally protruded toward the outer peripheral direction. The support portion main body 24 is integrally formed of synthetic resin or the like, but may be divided into a plurality of portions.

結束バンド26は、結束する内面側が平坦面に形成され、外面側は、図示しないが、多数の突条が間隔をおいて幅方向に形成されており、一端部及び巻回後の他端部側を支持部本体24に設けられたスリット状の取着孔に挿入することによって支持部本体24に取着されている。結束バンド26は、支持部本体24の取着孔に簡単に押し込んで挿入できるとともに、挿入後は、外面側の突条が支持部本体24の取着孔内の図示しない係止凹溝に係止し、抜け止め状態となる。したがって、結束バンド26は、支持部本体24の取着孔に挿入して引き締めるだけで簡単かつ強固にスリーブ41を締め付けて保持し支持し得る。   The binding band 26 is formed so that the inner surface side to be bound is a flat surface, and the outer surface side is not illustrated, but a large number of protrusions are formed in the width direction at intervals, one end portion and the other end portion after winding. The side is attached to the support portion main body 24 by being inserted into a slit-like attachment hole provided in the support portion main body 24. The binding band 26 can be easily pushed into the attachment hole of the support body 24 and inserted, and after the insertion, the outer ridges are engaged with a locking groove (not shown) in the attachment hole of the support body 24. It stops, and it will be in the retaining state. Therefore, the binding band 26 can simply and firmly tighten and hold and support the sleeve 41 simply by inserting it into the attachment hole of the support body 24 and tightening it.

次に、上記のように構成された配設体固定装置1を鉄筋32に固定し、コンクリート壁に配管孔を形成する方法を説明する。
最初に、固定後のスリーブ41と鉄筋32との離間距離に合致するよう、ボルト体21の雄ねじ部22の所定位置に固定具11を取付ける。それには、固定具11のコイル状の保持部13がボルト体21の外径より僅かに大きい内径に形成されているので、ボルト体21の雄ねじ部22をそのまま固定具11の保持部13内に挿通し、軸方向に所定位置まで移動させる。
Next, a method of fixing the arrangement body fixing device 1 configured as described above to the reinforcing bar 32 and forming a piping hole in the concrete wall will be described.
First, the fixture 11 is attached to a predetermined position of the male screw portion 22 of the bolt body 21 so as to match the separation distance between the sleeve 41 and the reinforcing bar 32 after fixing. For this purpose, since the coil-shaped holding portion 13 of the fixture 11 is formed to have an inner diameter slightly larger than the outer diameter of the bolt body 21, the male screw portion 22 of the bolt body 21 is directly placed in the holding portion 13 of the fixture 11. It is inserted and moved to a predetermined position in the axial direction.

ボルト体21の雄ねじ部22が所定位置まで移動したら、固定具11の両側の固定部12を把持してばね性を有する固定具11の弾性に抗して保持部13のコイルを更に巻回するようにして両側の連結部14が交差する部分の保持部13とは反対側の開き角度イを拡大させつつ両掛止部15の間隔を狭めてから掛止部15を鉄筋32に掛止させる。これにより、固定具11は、掛止部15が鉄筋32に弾性的に突張るようにして掛止し、鉄筋32に強固に固定される。固定具11が鉄筋32に固定された状態を図4及び図5に示す。   When the male screw portion 22 of the bolt body 21 moves to a predetermined position, the coil of the holding portion 13 is further wound against the elasticity of the fixing device 11 having spring properties by grasping the fixing portions 12 on both sides of the fixing device 11. In this way, the opening 15 on the side opposite to the holding portion 13 where the connecting portions 14 on both sides intersect is enlarged while the interval between the two locking portions 15 is narrowed, and then the hooking portion 15 is hooked on the reinforcing bar 32. . Thereby, the fixing tool 11 is hooked so that the hooking portion 15 elastically projects from the reinforcing bar 32, and is firmly fixed to the reinforcing bar 32. 4 and 5 show a state in which the fixing tool 11 is fixed to the reinforcing bar 32. FIG.

図5において、配設体固定装置1は、矢印で示すように、固定部12の弾性的な突張りによって両側の掛止部15に作用する押圧力と、保持部13の線材が鉄筋32と当接することによって保持部13に生ずる反力との釣り合いにより、鉄筋32に安定して強固に固定される。なお、固定具11の両側の連結部14は、当初、図2(a)に示すように、交差する部分の保持部13とは反対側の開き角度イは180度より小さい状態にあったのが、鉄筋32への固定後は、180度より大きくなっている。また、掛止部15は、鉄筋32に対して直交する向きに掛止し、固定具11は安定して鉄筋32に保持固定される。   In FIG. 5, the arrangement body fixing device 1 includes a pressing force acting on the latching portions 15 on both sides by the elastic projection of the fixing portion 12, and the wire rod of the holding portion 13 is a reinforcing bar 32. Due to the balance with the reaction force generated in the holding portion 13 by the contact, the reinforcing bar 32 is stably and firmly fixed. In addition, as shown in FIG. 2 (a), the connecting portions 14 on both sides of the fixture 11 were initially in a state where the opening angle i on the opposite side of the intersecting portion of the holding portion 13 was smaller than 180 degrees. However, after fixing to the reinforcing bar 32, it is larger than 180 degrees. Moreover, the latching | locking part 15 latches in the direction orthogonal to the reinforcing bar 32, and the fixing tool 11 is hold | maintained and fixed to the reinforcing bar 32 stably.

更に、鉄筋32への固定と同時に、固定具11の保持部13は、ボルト体21の外径より小さい内径に縮径されて、コイルの内部側の係合部16はボルト体21の雄ねじ部22に係合し、保持部13の線材の一部がボルト体21の雄ねじ部22の谷部内に嵌入する。そして、固定具11のばね性によって保持部13は、ボルト体21の雄ねじ部22に強く圧接する。この結果、ボルト体21は、固定具11の保持部13に対して軸方向に移動するのが阻止され、配設体支持部23は、鉄筋32から所定距離離間した位置に固定されるとともに、ボルト体21が保持部13に対して軸を中心に回動するのが防止される。これにより、配設体固定装置1の鉄筋32への固定は完了する。   Further, simultaneously with fixing to the reinforcing bar 32, the holding portion 13 of the fixing tool 11 is reduced in diameter to an inner diameter smaller than the outer diameter of the bolt body 21, and the engaging portion 16 on the inner side of the coil is the male screw portion of the bolt body 21. 22, and a part of the wire rod of the holding portion 13 is fitted into the valley portion of the male screw portion 22 of the bolt body 21. And the holding | maintenance part 13 presses strongly the external thread part 22 of the bolt body 21 with the spring property of the fixing tool 11. FIG. As a result, the bolt body 21 is prevented from moving in the axial direction with respect to the holding portion 13 of the fixture 11, and the arrangement body support portion 23 is fixed at a position spaced apart from the reinforcing bar 32 by a predetermined distance. The bolt body 21 is prevented from rotating about the axis with respect to the holding portion 13. Thereby, fixation to the reinforcing bar 32 of the arrangement body fixing device 1 is completed.

配設体固定装置1の鉄筋32への固定が完了したら、スリーブ41の外周壁をボルト体21の配設体当接部24cに当接させつつスリーブ41を配設体支持部23に配置し、結束バンド26を引き締めてボルト体21に支持させる。その後、対向する型枠内にコンクリートを打設し、硬化後、脱型し、スリーブ41を抜き取ることにより、コンクリート壁に配管を挿通するための配管孔がコンクリート壁の厚さ方向に形成される。なお、手順として、スリーブ41は、配設体固定装置1を鉄筋32に固定する前に、ボルト体21の配設体支持部23に支持させてもよい。   When the fixing of the arrangement body fixing device 1 to the reinforcing bar 32 is completed, the sleeve 41 is arranged on the arrangement body support section 23 while the outer peripheral wall of the sleeve 41 is brought into contact with the arrangement body abutting section 24c of the bolt body 21. Then, the binding band 26 is tightened and supported by the bolt body 21. Thereafter, concrete is placed in the opposing mold, cured, removed from the mold, and the sleeve 41 is removed, whereby a pipe hole for inserting the pipe into the concrete wall is formed in the thickness direction of the concrete wall. . As a procedure, the sleeve 41 may be supported by the arrangement body support portion 23 of the bolt body 21 before the arrangement body fixing device 1 is fixed to the reinforcing bar 32.

次に、第一実施形態の固定具11及び配設体固定装置1の作用を説明する。
固定具11は、ばね性を有するとともに、コイル状の保持部13は、ボルト体21の外径より大きい内径に形成され、固定部12を鉄筋32に固定することでボルト体21の外径より小さい内径に縮径されるよう形成されているので、固定具11の線材の弾性に抗して固定部12を鉄筋32に固定すれば、同時に保持部13はボルト体21の外径より小さい内径に縮径されて係合部16がボルト体21の雄ねじ部22に係合し、ボルト体21が軸方向に移動するのが阻止される。このため、固定具11の保持部13をボルト体21の雄ねじ部22の所定位置に配置した後、配設体固定装置1を鉄筋32に固定することにより、自ずとボルト体21を雄ねじ部22の所定位置において保持部13に保持させることができる。そして、固定部12は、掛止部15をばねの付勢力に抗して鉄筋32に掛け止めするだけで、簡単に鉄筋32に固定できる。したがって、固定具11の掛止部15を鉄筋32に掛止するだけの簡単な操作で、ボルト体21を鉄筋32に固定できると同時に、簡単に位置調整して、スリーブ41を鉄筋32に対して所定距離離間した一定位置に固定することができる。
Next, the operation of the fixture 11 and the arrangement body fixing device 1 according to the first embodiment will be described.
The fixture 11 has a spring property, and the coil-shaped holding portion 13 is formed to have an inner diameter larger than the outer diameter of the bolt body 21. By fixing the fixing portion 12 to the reinforcing bar 32, the outer diameter of the bolt body 21 is secured. Since the diameter is reduced to a small inner diameter, if the fixing portion 12 is fixed to the reinforcing bar 32 against the elasticity of the wire rod of the fixing tool 11, the holding portion 13 has an inner diameter smaller than the outer diameter of the bolt body 21 at the same time. The engagement portion 16 is engaged with the male screw portion 22 of the bolt body 21 and the bolt body 21 is prevented from moving in the axial direction. For this reason, after arrange | positioning the holding | maintenance part 13 of the fixing tool 11 to the predetermined position of the external thread part 22 of the bolt body 21, the bolt body 21 is naturally attached to the external thread part 22 by fixing the arrangement body fixing device 1 to the reinforcing bar 32. It can be held by the holding unit 13 at a predetermined position. And the fixing | fixed part 12 can be easily fixed to the reinforcing bar 32 only by latching the hooking part 15 on the reinforcing bar 32 against the urging force of the spring. Therefore, the bolt body 21 can be fixed to the reinforcing bar 32 by a simple operation of simply hooking the hooking portion 15 of the fixing tool 11 to the reinforcing bar 32, and at the same time, the position of the bolt body 21 can be easily adjusted, and the sleeve 41 with respect to the reinforcing bar 32. Can be fixed at a fixed position separated by a predetermined distance.

また、配設体固定装置1は、固定具11を1本のばね性を有する線材を折り曲げ加工して形成し、コイル状に巻回してなる保持部13にボルト体21を挿通して保持させるだけの簡易な構成で形成することができる。
更に、固定具11は、保持部13が線材をコイル状に複数巻回して形成されているので、保持部13を簡易な構成で形成できるとともに、所定のばね性を安定して得ることができる。
Moreover, the arrangement | positioning body fixing device 1 inserts and hold | maintains the bolt body 21 in the holding | maintenance part 13 which forms the fixing tool 11 by bending the wire material which has one spring property, and is wound in coil shape. It can be formed with only a simple configuration.
Furthermore, since the holding part 13 is formed by winding the wire rod in a plurality of coils in the fixture 11, the holding part 13 can be formed with a simple configuration and a predetermined spring property can be stably obtained. .

加えて、鉄筋32への固定後、固定具11の係合部16がボルト体21の雄ねじ部22に係合した状態で、保持部13はボルト体21に圧接してボルト体21が軸を中心に回動するのを防止し、ボルト体21は強固に固定具11に固定される。
また、ばね性を有する固定具11の復元力によって固定部12の掛止部15は鉄筋32に弾性的に強く突張って掛止し、固定具11は鉄筋32に強固に固定される。
これにより、ボルト体21に支持されたスリーブ41は鉄筋32に対して一定姿勢に安定して強固に固定される。
In addition, after fixing to the reinforcing bar 32, the holding part 13 is pressed against the bolt body 21 in a state where the engaging part 16 of the fixing tool 11 is engaged with the male screw part 22 of the bolt body 21, and the bolt body 21 rotates the shaft. The bolt body 21 is firmly fixed to the fixture 11 while preventing the pivoting to the center.
Further, the latching portion 15 of the fixing portion 12 is elastically strongly stretched and hooked to the reinforcing bar 32 by the restoring force of the fixing tool 11 having spring properties, and the fixing tool 11 is firmly fixed to the reinforcing bar 32.
Thereby, the sleeve 41 supported by the bolt body 21 is stably and firmly fixed to the reinforcing bar 32 in a fixed posture.

ところで、本実施形態の固定具11は、固定部12の掛止部15が弾性的に強く突張って鉄筋32に掛止されるので、施工途中で鉄筋32に対する配設体固定装置1の固定位置を変更したりする必要が生じたときに、一旦鉄筋32に固定した配設体固定装置1を取り外すのが困難なことがある。   By the way, as for the fixing tool 11 of this embodiment, since the latching | locking part 15 of the fixing | fixed part 12 stretches elastically strongly, and is latched by the reinforcing bar 32, fixing of the arrangement body fixing apparatus 1 with respect to the reinforcing bar 32 in the middle of construction. When it is necessary to change the position, it may be difficult to remove the arrangement body fixing device 1 once fixed to the reinforcing bar 32.

そこで、固定具11の変形例として、図6に示すように、一方の固定部12に、線材を1回ループ状に巻いたループ部17を形成してもよい。この固定具11の場合、図7に示すように、鉄筋32に固定された固定具11に対してマイナスドライバ51等の工具をループ部17に差し込んでこじることにより、容易に一方の掛止部15の掛止を解除し、鉄筋32から固定具11を取り外すことができる。なお、ループ部17は、両側の固定部12に設けてもよい。また、ループ部17に代えて他の形状のものを設けてもよい。   Therefore, as a modified example of the fixture 11, as shown in FIG. 6, a loop portion 17 in which a wire is wound once in a loop shape may be formed on one fixing portion 12. In the case of this fixture 11, as shown in FIG. 7, by inserting a tool such as a flathead screwdriver 51 into the loop portion 17 with respect to the fixture 11 fixed to the reinforcing bar 32, one latching portion can be easily formed. 15 can be released and the fixture 11 can be removed from the reinforcing bar 32. In addition, you may provide the loop part 17 in the fixing | fixed part 12 of both sides. Further, instead of the loop portion 17, another shape may be provided.

加えて、ボルト体21の支持部本体24には、スリーブ41を支持するために、結束バンド26が取付けられているが、他の結束部材、例えば、紐体やバインド線などを取付けてスリーブ41を支持させてもよい。   In addition, a binding band 26 is attached to the support body 24 of the bolt body 21 in order to support the sleeve 41. However, other binding members, for example, a string body or a binding wire, are attached to the sleeve 41. May be supported.

次に、この第一実施形態において、配設体固定装置1は、1つの配設体支持部23を備え、1個のスリーブ41を支持する構成としているが、図8に示すように、1つの固定具11、1本の雄ねじ部22に対して、2つの配設体支持部23を備え、計2個のスリーブ41を支持する構成とすることもできる。即ち、図8に示す配設体固定装置1は、図1、図2に示す配設体固定装置1と比べてボルト体21の雄ねじ部22を長く形成し、長さ方向の略中間部に1つの固定具11を取付けるとともに、その固定具11を挟んでその雄ねじ部22の両端部それぞれに配設体支持部23をほぼ対称的に備えた構成としている。この場合、コンクリート壁には、配管を挿通させるための配管孔を間隔をあけて平行に2個形成することができ、これにより、多数の配管を2つに分割して挿通させたり、種類の異なる配管を区別して挿通させることができる。   Next, in the first embodiment, the arrangement body fixing device 1 includes one arrangement body support portion 23 and supports one sleeve 41. As shown in FIG. The two fixtures 11 and the single male screw portion 22 may be provided with two arrangement body support portions 23 to support a total of two sleeves 41. That is, the arrangement body fixing device 1 shown in FIG. 8 has a longer male threaded portion 22 of the bolt body 21 than the arrangement body fixing device 1 shown in FIGS. A single fixing tool 11 is attached, and arrangement body support portions 23 are provided substantially symmetrically at both ends of the male screw portion 22 with the fixing tool 11 interposed therebetween. In this case, the concrete wall can be formed with two pipe holes parallel to each other with a gap between them so that a large number of pipes can be divided into two parts. Different piping can be distinguished and inserted.

〈第二実施形態〉
次に、本発明の第二実施形態の固定具11及び配設体固定装置1を図9に基づいて説明する。
基本的には、鉄筋32への固定前において、第一実施形態の固定具11の保持部13は、ボルト体21の雄ねじ部22の外径より僅かに大きい内径に形成されているとともに、両側の連結部14は、交差する部分の保持部13とは反対側の開き角度イが180度より小さく設定されているのに対し、第二実施形態の固定具11の場合は、保持部13は、ボルト体21の雄ねじ部22の外径より僅かに小さい内径に形成されているとともに、交差する部分の保持部13とは反対側の開き角度イは180度より大きく設定されている点において、第二実施形態の固定具11は、第一実施形態の固定具11と相違する。その他の点においては、両者はほぼ共通する。
<Second embodiment>
Next, the fixture 11 and the arrangement | positioning body fixing device 1 of 2nd embodiment of this invention are demonstrated based on FIG.
Basically, the holding part 13 of the fixture 11 of the first embodiment is formed to have an inner diameter slightly larger than the outer diameter of the male screw part 22 of the bolt body 21 before being fixed to the reinforcing bar 32, and both sides. The connecting portion 14 has an opening angle i on the opposite side of the intersecting portion of the holding portion 13 smaller than 180 degrees, whereas in the case of the fixture 11 of the second embodiment, the holding portion 13 is In addition, the inner diameter of the bolt body 21 is slightly smaller than the outer diameter of the male thread portion 22 and the opening angle i on the opposite side of the intersecting portion of the holding portion 13 is set to be larger than 180 degrees. The fixture 11 of the second embodiment is different from the fixture 11 of the first embodiment. In other respects, they are almost the same.

即ち、第二実施形態の固定具11は、図9(a)において、鉄筋32への固定前において、保持部13の内径Dは、ボルト体21の外径より僅かに小さく形成されているので、そのままでは、内部にボルト体21の雄ねじ部22を挿入することはできない状態にある。
また、両側の連結部14は、交差する部分の保持部13とは反対側の開き角度イは180度より大きく設定され、即ち、交差する部分の保持部13と同側の開き角度ロは180度より小さく設定されている。このときの両側の固定部12の間隔はL1である。更に、この両連結部14の開き角度ロ及び固定部12の間隔L1は、固定具11を鉄筋32に固定した後の図9(c)に示す両連結部14が交差する部分の保持部13と同側の開き角度ロ’及び固定部12の間隔L3と略同一に設定されている。
That is, in the fixing device 11 of the second embodiment, the inner diameter D of the holding portion 13 is slightly smaller than the outer diameter of the bolt body 21 before being fixed to the reinforcing bar 32 in FIG. As it is, the male threaded portion 22 of the bolt body 21 cannot be inserted inside.
Further, the opening angle i on the opposite side to the holding portion 13 at the intersecting portion is set to be greater than 180 degrees, that is, the opening angle b on the same side as the holding portion 13 at the intersecting portion is 180 degrees. It is set smaller than the degree. At this time, the interval between the fixing portions 12 on both sides is L1. Furthermore, the opening angle b of both the connecting portions 14 and the distance L1 between the fixing portions 12 are the holding portions 13 at the portions where the connecting portions 14 shown in FIG. 9C intersect after the fixing tool 11 is fixed to the reinforcing bar 32. Are set to be substantially the same as the opening angle b ′ on the same side and the interval L3 of the fixing portion 12.

このように構成された第二実施形態の配設体固定装置1を鉄筋32に固定するには、最初の固定具11が図9(a)の状態においては、保持部13は、ボルト体21の雄ねじ部22の外径より僅かに小さい内径Dに形成され、保持部13内にボルト体21の雄ねじ部22を挿入することはできないので、両側の固定部12を把持してばねの付勢力に抗して保持部13を軸に白抜き矢印の方向に押し拡げて、図9(b)のように、両連結部14がほぼ水平状態となるようにする。これに伴い、両固定部12の間隔は、図9(a)のL1から図9(b)のL2に拡大する。すると、保持部13のコイルの内径は、僅かに拡径し、ボルト体21の雄ねじ部22の外径より僅かに大きくなって、保持部13内に雄ねじ部22を挿入することが可能となる。   In order to fix the arrangement body fixing device 1 of the second embodiment configured as described above to the reinforcing bar 32, the holding unit 13 is the bolt body 21 when the first fixing tool 11 is in the state of FIG. Since the male screw portion 22 of the bolt body 21 cannot be inserted into the holding portion 13, the fixing portion 12 on both sides is gripped and the spring biasing force is formed. Against this, the holding portion 13 is pushed and expanded in the direction of the white arrow about the axis, so that both the connecting portions 14 become substantially horizontal as shown in FIG. 9B. Along with this, the interval between the two fixing portions 12 increases from L1 in FIG. 9A to L2 in FIG. 9B. Then, the inner diameter of the coil of the holding portion 13 is slightly increased, and becomes slightly larger than the outer diameter of the male screw portion 22 of the bolt body 21, so that the male screw portion 22 can be inserted into the holding portion 13. .

そこで、保持部13内にボルト体21の雄ねじ部22を挿入し、続いて、両側の固定部12の押し曲げを緩めて解放する。すると、両側の固定部12及び連結部14は保持部13を軸に図9(b)の矢印方向に回動して元の図9(a)の状態に弾性復帰するとともに、保持部13は付勢力による復元によって縮径され、保持部13がボルト体21の雄ねじ部22に係合し、保持部13はボルト体21を保持する。この後、引き続いて、保持部13がボルト体21を保持した状態で、固定具11の両側の固定部12を把持し、ばねの付勢力に抗して、保持部13を軸に図9(a)の白抜き矢印とは反対方向に更に押し曲げて両固定部12の間隔を更に狭めてつつ、両側の掛止部15を強制的に鉄筋32に掛止させる。   Therefore, the male screw portion 22 of the bolt body 21 is inserted into the holding portion 13, and subsequently, the pushing and bending of the fixing portions 12 on both sides is loosened and released. Then, the fixing part 12 and the connecting part 14 on both sides rotate about the holding part 13 in the direction of the arrow in FIG. 9 (b) and elastically return to the original state of FIG. 9 (a). The diameter is reduced by the restoration by the urging force, the holding portion 13 engages with the male screw portion 22 of the bolt body 21, and the holding portion 13 holds the bolt body 21. Thereafter, in the state where the holding part 13 holds the bolt body 21, the fixing parts 12 on both sides of the fixing tool 11 are gripped, and the holding part 13 is used as a shaft against the biasing force of the spring as shown in FIG. The hooks 15 on both sides are forcibly hooked to the reinforcing bars 32 while further narrowing the distance between the two fixing parts 12 by further pushing and bending in the direction opposite to the white arrow in a).

掛止後は、固定具11は、図9(c)に示すように、図9(a)のほぼ設定当初の状態に弾性復帰し、両固定部12の間隔はL3となる。以上により、配設体固定装置1は、固定具11の掛止部15が弾性的に突張った状態で強固に鉄筋32に固定され、スリーブ41は、鉄筋32から所定距離離間した一定位置に固定され支持される。   After the hooking, as shown in FIG. 9 (c), the fixture 11 is elastically restored to the initial setting state shown in FIG. 9 (a), and the distance between the two fixing portions 12 is L3. As described above, the arrangement body fixing device 1 is firmly fixed to the reinforcing bar 32 in a state where the latching portion 15 of the fixing tool 11 is elastically stretched, and the sleeve 41 is in a fixed position spaced apart from the reinforcing bar 32 by a predetermined distance. Fixed and supported.

このように、第一実施形態では、固定具11の保持部13は、該ボルト体21の外径より大きい内径Dに形成され、固定部12を鉄筋32に固定することでボルト体21の外径より小さい内径Dに縮径されて係合部16がボルト体21の雄ねじ部22に係合するのに対し、第二実施形態では、当初、ボルト体21の外径より小さい内径Dに形成された固定具11の保持部13が、両側の連結部14をほぼ水平状態に押し拡げて両固定部12の間隔を変更してL1からL2に拡大することにより、ボルト体21の外径より大きい内径Dに拡径されてボルト体21は軸方向に挿入し移動可能となるので、保持部13内にボルト体21の雄ねじ部22を挿入し、その後、両側の固定部12の拡張を緩めて解放することにより、ばねの付勢力による復元によって縮径されて係合部16はボルト体21の雄ねじ部22に係合する。   As described above, in the first embodiment, the holding portion 13 of the fixture 11 is formed to have an inner diameter D that is larger than the outer diameter of the bolt body 21, and the fixing portion 12 is fixed to the reinforcing bar 32, thereby The engagement portion 16 is reduced to an inner diameter D smaller than the diameter and engages with the male screw portion 22 of the bolt body 21, whereas in the second embodiment, the inner diameter D is initially formed smaller than the outer diameter of the bolt body 21. The holding part 13 of the fixing tool 11 is expanded from L1 to L2 by changing the distance between the two fixing parts 12 by expanding the connecting parts 14 on both sides in a substantially horizontal state, thereby increasing the outer diameter of the bolt body 21. Since the bolt body 21 is expanded to have a large inner diameter D and can be inserted and moved in the axial direction, the male threaded portion 22 of the bolt body 21 is inserted into the holding portion 13 and then the expansion of the fixing portions 12 on both sides is loosened. Release the A reduced diameter by the engagement portion 16 engages the external thread portion 22 of the bolt body 21.

この第二実施形態の配設体固定装置1は、固定具11が付勢力による復元によって固定前とほぼ同じ状態となって鉄筋32に固定されるが、基本的には、第一実施形態の配設体固定装置1と同様に作用する。
なお、第二実施形態においては、固定時に固定具11は付勢力により復元するが、鉄筋32への固定後の状態は、必ずしも設定当初と略同一であることは要しない。
The arrangement body fixing device 1 of the second embodiment is fixed to the reinforcing bar 32 in a state almost the same as before fixing by the restoration by the biasing force. It operates in the same manner as the arrangement body fixing device 1.
In addition, in 2nd embodiment, although the fixing tool 11 is restored | restored by urging | biasing force at the time of fixation, the state after fixing to the reinforcing bar 32 does not necessarily need to be substantially the same as the initial stage of setting.
